The recent discoveries at Stonehenge, including ritual monuments, burial mounds and a long barrow, are wonderful examples of how archaeological geophysics can be used in areas where excavation is hard to justify.

Using powerful ground-penetrating radar, investigators working around Stonehenge have detected a trove of previously unknown burial mounds, chapels, shrines, pits — and most remarkable of all — a massive megalithic monument made up of more than 50 giant stones buried along a 1,082-foot-long c-shaped enclosure.
